Embed Google Map from Google Fusion Tables

I've created some custom Google maps using Google Fusion Tables but am unable to see the maps on my site when I paste in the iframe code. A post over at the Google Fusion support boards indicates that the reason is because while "maps.google.com" is on the whitelist for embedding maps, "www.google.com/fusiontables" is not.

I contacted WordPress staff about this issue, and they confirmed it is not currently possible to embed Fusion Table maps. They expressed interest in the feature though and it seems like it's something that could be implemented at some point in the future. However, they implied that implementation is not as easy as flipping a switch.

Hopefully we'll get this feature soon. Thanks for all the hard work WordPress Team!
